Hi all,
I'm thinking about doing a parallel install with a friend on a supercharged 1zz engine.
I'm thinking ua4c. I saw on dcwerx YouTube cutting a couple of traces and desoldering a blob somewhere on the board. I believe this is to allow the two ecus to read the IAT, TPS, CLT at the same time.
I Also read that sometime the parallel install is possible and sometimes not, depends on the ECU we're dealing with.
So, is there a decent write up anywhere for how to figure out if it's possible on this engine and confirm what I'd need to do?

Thanks

Jon
